Every now and then I jump on the garrettmotion website to check out turbine housing options and such for their latest models. Looks like they just came out with an interesting lineup of very small turbochargers with the latest aero, but journal bearing center sections and ductile iron housings. The two that particularly caught my eye were the GBC22-300 and 350, very small rotor groups capable of 300 and 350hp respectively. These seem like the perfect unit for someone looking for something like an S15 turbo, but with better response and higher output. Looks like retail is around $900 too, so really a bargain all around!
